The opening round of group-stage matches at the Nitto ATP Finals has concluded. Kazakhstani player Alexander Bublik is present at the tournament in Turin as the first alternate.
Bublik, currently world No. 11, will join the competition if any of the players withdraw from the tournament. The likelihood of this happening is not negligible, given the injuries and fatigue that often accumulate by the end of the season. For example, during the same women’s tournament — won by Kazakhstani Elena Rybakina — Russian player Ekaterina Alexandrova replaced Madison Keys from the U.S.
